MAX1951 Datasheet PDF - Maxim Integrated

Description

●The MAX1951/MAX1952 high-efficiency, DC-to-DC step-down switching regulators deliver up to 2A of output current. The devices operate from an input voltage range of 2.6V to 5.5V and provide an output voltage from 0.8V to VIN, making the MAX1951/MAX1952 ideal for on-board postregulation applications. The MAX1951 total output error is less than 1% over load, line, and temperature.

●The MAX1951/MAX1952 operate at a fixed frequency of 1MHz with an efficiency of up to 94%. The high operating frequency minimizes the size of external components. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protection improve design reliability.

●The MAX1951 provides an adjustable output from 0.8V to VIN, whereas the MAX1952 has a preset output of 1.8V. Both devices are available in a space-saving 8-pin SO package.
